The invention discloses a sounder module which comprises a sounder unit and an external shell for containing the sounder unit; the sounder unit comprises a magnetic circuit system; the magnetic circuit system comprises a magnetic conductive plate, a magnet and a magnet yoke which are sequentially assembled; moreover, the external shell of the sounder module forms a magnetic circuit system framework for fixing the sounder; and the magnetic circuit system and the external shell are of an integrated injection molding structure, the internal dimension of the sounder unit can be increased, and also the product design is simplified, which is good for the minitype design of the sounder module. According to the assembling method provided by the invention, the external shell and the magnetic circuit system are assembled by the steps as follows: a. firstly assembling the magnetic conductive plate, the magnet and the magnet yoke sequentially; b. placing the magnetic conductive plate, the magnet and the magnet yoke after assembling into an injection molding jig which forms the external shell; and c. adding an injection molding material, molding the magnetic circuit system and the external shell of the sounder module integrally, assembling in advance through the magnetic circuit system, molding with the external shell integrally, thus the assembling process and working procedures are simplified, and the production cost is lowered.
Description
technical field [0001] The present invention relates to the technical field of electroacoustic conversion, in particular to a sounder module and an assembly method of the sounder module. Background technique [0002] With the rapid development of the consumer electronics market, a large number of miniature electro-acoustic components, such as sounders, have been widely used; in practical applications, the sounder unit is generally placed in a module contained by an external shell , to match the acoustic performance of the sound generator. [0003] This kind of sounder module structure, due to the structural size of the sounder unit body and the design requirements of the acoustic cavity space, the size of the sounder unit is limited, and the product structure design is relatively complicated; at the same time, due to the need to consider the assembly of the sounder unit and the external shell , The design process of the product is relatively complicated, and the assembly pr...
